said diaphragm membrane 70, which is extrude-molded by semi-rigid elastic material and to be placed on the pump head body 60, includes a pair of parallel outer raised brim 71 and inner raised brim 72 as well as five evenly spaced radial raised partition ribs 73 such that each end of radial raised partition rib 73 connects with the inner raised brim 72, five equivalent piston acting zones 74 are formed and partitioned by the radial raised partition ribs 73, wherein each piston acting zone 74 has an acting zone hole 75 created therein in correspondence with each female-threaded bore 54 in the tubular eccentric roundel 52 of the eccentric roundel mount 50 respectively, and an annular positioning protrusion 76 for each acting zone hole 75 is formed at the bottom side of the diaphragm membrane 70 (as shown in FIGS. 8 through 10); each said pumping piston 80, which is respectively disposed in each corresponding piston acting zones 74 of the diaphragm membrane 70, has a tiered hole 81 run through thereof, after having each annular positioning protrusion 76 in the diaphragm membrane 70 inserted into each corresponding annular positioning dent 55 in the tubular eccentric roundel 52 of the eccentric roundel mount 50, by running fastening screw 1 through the tiered hole 81 of each pumping piston 80 and the acting zone hole 74 of each corresponding piston acting zone 74 in the diaphragm membrane 70, the diaphragm membrane 70 and five pumping pistons 80 can be securely screwed into each female-threaded bore 54 of corresponding five tubular eccentric roundels 52 in the eccentric roundel mount 50 (as enlarged view shown in FIG. 11 of association); said piston valvular assembly 90, which suitably covers on the diaphragm membrane 70, includes a downward outlet raised brim 91 to insert between the outer raised brim 71 and inner raised brim 72 in the diaphragm membrane 70, a central dish-shaped round outlet mount 92 having a central positioning bore 93 with five equivalent sectors each of which contains multiple evenly circum-located outlet ports 95, a T-shaped plastic anti-backflow valve 94 with a central positioning shank, and five circumjacent inlet mounts 96, each of which includes multiple evenly circum-located inlet ports 97 and a inverted central piston disk 98 respectively so that each piston disk 98 serves as a valve for each corresponding group of multiple inlet ports 97, wherein the central positioning shank of the plastic anti-backflow valve 94 mates with the central positioning bore 93 of the central outlet mount 92 such that multiple outlet ports 95 in the central round outlet mount 92 are communicable with five inlet mounts 96, and a hermetical preliminary-compressing chamber 26 is formed between each inlet mount 96 and corresponding piston acting zone 74 in the diaphragm membrane 70 upon the downward outlet raised brim 91 having inserted between the outer raised brim 71 and inner raised brim 72 in the diaphragm membrane 70 such that one end of each preliminary-compressing chamber 26 is communicable with each corresponding inlet ports 97 (as enlarged view shown in FIG. 11 of association); and said pump head cover 20, which covers on the pump head body 60 to encompass the piston valvular assembly 90, pumping piston 80 and diaphragm membrane 70 therein, includes a water inlet orifice 21, a water outlet orifice 22, and several fastening bores 23 while a tiered rim 24 and an annular rib ring 25 are disposed in the bottom inside of said pump head cover 20 such that the outer brim for the assembly of diaphragm membrane 70 and piston valvular assembly 90 can hermetically attach on the tiered rim 24 (as enlarged view shown in FIG. 11 of association), wherein a high-compressing chamber 27 is configured between cavity formed by the inside wall of the annular rib ring 25 and the central outlet mount 92 of the piston valvular assembly 90 upon having the bottom of the annular rib ring 25 closely covered on the brim of the central outlet mount 92 (as shown in FIG. 11).

By running each fastening bolt 2 through the each corresponding fastening bores 23 of pump head cover 20 and each corresponding fastening bore 63 in the pump head body 60, then putting a nut 3 onto each fastening bolt 2 to securely screw the pump head cover 20 and pump head body 60 with the motor upper chassis 30 via each corresponding fastening bore 33 in the motor upper chassis 30 so that the whole assembly of the five-compressing-chamber diaphragm pump is finished (as shown in FIGS. 1 and 11).

Please refer to FIGS. 12 and 13, which are illustrative figures for the operation of “conventional five-compressing-chamber diaphragm pump”.

Firstly, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five tubular eccentric roundels 52 on the eccentric roundel mount 50 orderly move in up-and-down reciprocal stroke constantly;

Secondly, meanwhile, five pumping pistons 80 and five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five tubular eccentric roundels 52 to move in up-and-down displacement;

Thirdly, when the tubular eccentric roundel 52 moves in “down stroke” with pumping piston 80 and piston acting zone 74 in down displacement, the piston disk 98 in the piston valvular assembly 90 is pushed into “open” status so that the tap water W can flow into the preliminary-compressing chamber 26 orderly via water inlet orifice 21 in the pump head cover 20 and inlet ports 97 in the piston valvular assembly 90 (as shown in FIG. 12 and arrowhead indication W in enlarged view of association);

Fourthly, when the tubular eccentric roundel 52 moves in “up stroke” with pumping piston 80 and piston acting zone 74 in up displacement, the piston disk 98 in the piston valvular assembly 90 is pulled into “close” status to compress the tap water W in the preliminary-compressing chamber 26 to increase the water pressure therein up to range of 100 psi-150 psi and become into pressurized water Wp with result that the plastic anti-backflow valve 94 in the piston valvular assembly 90 is pushed to “open” status;

Fifthly, when the plastic anti-backflow valve 94 in the piston valvular assembly 90 is pushed to “open” status, the pressurized water Wp in the preliminary-compressing chamber 26 is directed into high-compressing chamber 27 via group of outlet ports 95 for the corresponding sector in central outlet mount 92, then expelled out of the water outlet orifice 22 in the pump head cover 20 (as shown in FIG. 13 and arrowhead indication Wp in enlarged view of association); and

Finally, with orderly iterative action for each group of outlet ports 95 for five sectors in central outlet mount 92, the pressurized water Wp is constantly discharged out of the conventional five-compressing-chamber diaphragm pump for being further RO-filtered by the RO-cartridge so that the final filtered pressurized water Wp can be used in the RO (Reverse Osmosis) purifier or RO water purification system, which is popularly installed on the water supplying apparatus in either the settled home, recreational vehicle or mobile home.

Referring to FIGS. 14 and 15, a primary serious drawback has long-lasting existed in the foregoing conventional five-compressing-chamber diaphragm pump is described as below. As described previously, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five tubular eccentric roundels 52 on the eccentric roundel mount 50 orderly move in up-and-down reciprocal stroke constantly, meanwhile five pumping pistons 80 and five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five tubular eccentric roundels 52 to move in up-and-down displacement so that equivalently a reiterative acting force F constantly acting on the five piston acting zones 74 with a length of moment arm L1 obtained from the outer raised brim 71 to the peripheral of the annular positioning protrusion 76 (as shown in FIG. 15). Thereby, a resultant torque is created by the acting force F multiplying the length of moment arm L1 as shown by the formula “torque=acting force F×length of moment arm L1” namely. However, the resultant torque causes the whole conventional five-compressing-chamber diaphragm pump to vibrate directly. With high rotational speed of the motor output shaft 11 in the motor 10 up to range of 800-1200 rpm, the vibrating strength caused by alternately acting of five tubular eccentric roundels 52 can reach unacceptable condition persistently.

In view of the all drawbacks aforesaid in the conventional five-compressing-chamber diaphragm pump, as shown in FIG. 16, a cushion base 100 with a pair of wing plates 101 is always bolstered as supporting supplementary such that each wing plate 101 is further sleeved by a rubber shock absorber 102 for vibration suppressing enhancement. Upon installation the conventional five-compressing-chamber diaphragm pump in the water supplying apparatus in the settled home or mobile home, the cushion base 100 is firmly screwed onto the housing C of the reverse osmosis purification unit by means of suitable fastening screws 103 and corresponding nuts 104. However, the practical vibration suppressing efficiency of using foregoing cushion base 100 with wing plates 101 and rubber shock absorber 102 only affects to the primary vibrating drawback aforesaid and in limited degree because the overall “resonant shakes” aforesaid will incur the vibration of the housing C for the reverse osmosis purification unit to become stronger with harassing noise. Other than the primary vibrating drawback aforesaid, the water pipe P connected on the water outlet orifice 22 of the pump head cover 20 will synchronously “shake” in resonance with the “vibration” aforesaid (as hypothetic line P for illustrative view a of association shown in FIG. 16). Thereby, the synchronous “shake” of the water pipe P will further incur other rest parts of the “conventional compressing diaphragm pump” to simultaneously “shake” also. Therefore, after having served for a certain period, the “water leakage” of the “conventional compressing diaphragm pump” will happen due to gradually loosed connection between water pipe P and water outlet orifice 22 as well as gradually loosed fitness among other rest parts incurred by the “shake” effects. For the issues of overall “resonant shakes” and the “water leakage” for the conventional five-compressing-chamber diaphragm pump aforesaid are incurred by the foregoing primary vibrating drawback. Therefore, how to substantially reduce all the drawbacks associated with the operating vibration for the five-compressing-chamber diaphragm pump becomes an urgent and critical issue.

Besides, as described previously, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five tubular eccentric roundels 52 on the eccentric roundel mount 50 orderly move in up-and-down reciprocal stroke constantly, and five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five tubular eccentric roundels 52 to move in up-and-down displacement so that equivalently a reiterative acting force F constantly acting on the bottom side of each said piston acting zone 74. Meanwhile a plurality of rebounding force Fs is created to react the acting force F exerting on the bottom side of diaphragm membrane 70 with different components distributed over entire bottom area of each corresponding piston acting zone 74 in the diaphragm membrane 70 (as shown in FIG. 18) so that a “squeezing phenomenon” happens on the partial portion of the diaphragm membrane 70, which is incurred by the rebounding force Fs. Among all distributed components of the rebounding force Fs, the component force happened at the contacting bottom position P of the diaphragm membrane 70 with the rounded shoulder 57 of the horizontal top face 53 in the tubular eccentric roundel 52 is maximum so that the “squeezing phenomenon” happened here is also maximum (as shown in FIG. 18). With rotational speed for the motor output shaft 11 of the motor 10 reaching a range of 800-1200 rpm, each bottom position P at the piston acting zone 74 of the diaphragm membrane 70 is suffered from the “squeezing phenomenon” in a frequency of five times per second. Under such circumstance, the bottom position P of the diaphragm membrane 70 is always the first broken place for entire conventional five-compressing-chamber diaphragm pump, which is the essential cause for not only shortening the service lifespan but also terminating normal function of the conventional five-compressing-chamber diaphragm pump. Therefore, how to substantially reduce all the drawbacks associated with the “squeezing phenomenon” caused by the reiterative acting force F constantly acting on the bottom side of each said piston acting zone 74 of the diaphragm membrane 70, which is incurred by the tubular eccentric roundel 52, for the conventional five-compressing-chamber diaphragm pump also becomes an urgent and critical issue.

Referring to FIGS. 19 and 21, they are illustrative figures for the structure and operation of conventional five-compressing-chamber diaphragm pump with another piston valvular assembly 900. The piston valvular assembly 900 includes a downward outlet raised brim 901 to insert between the outer raised brim 71 and inner raised brim 72 in the diaphragm membrane 70, a central round outlet mount 902, five equivalent sector zones evenly distributed in the outlet mount 902 such that each of sectors composed of a zone positioning bore 903, a T-shaped zone anti-backflow valve 904 with a zone positioning shank as well as a group of multiple evenly circum-located outlet ports 905 around each corresponding zone positioning bore 903, and five circumjacent inlet mounts 906 such that each of which includes a group of multiple evenly circum-located inlet ports 907 and a inverted central piston disk 908 respectively so that each piston disk 908 serves as a valve for each corresponding group of multiple inlet ports 907 (as shown in FIG. 19), wherein each zone positioning shank of the zone anti-backflow valve 904 mates with the zone positioning bore 903 of the central outlet mount 902 such that each group of multiple outlet ports 905 of each sector zone in the central round outlet mount 902 are communicable with each corresponding inlet mount 906, and a hermetical preliminary-compressing chamber 26 is formed between each inlet mount 906 and each corresponding piston acting zone 74 in the diaphragm membrane 70 upon the downward outlet raised brim 901 having inserted between the outer raised brim 71 and inner raised brim 72 in the diaphragm membrane 70 such that one end of each preliminary-compressing chamber 26 is communicable with each corresponding group of multiple inlet ports 907 (as enlarged view shown in FIG. 21 of association).

By running each fastening bolt 2 through the each corresponding fastening bores 23 of pump head cover 20 and each corresponding fastening bore 63 in the pump head body 60, then putting a nut 3 onto each fastening bolt 2 to securely screw the pump head cover 20 and pump head body 60 with the motor upper chassis 30 via each corresponding fastening bore 33 in the motor upper chassis 30 so that the whole assembly of the five-compressing-chamber diaphragm pump is finished (as shown in FIGS. 1 and 21).

Please refer to FIG. 21.

Firstly, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five eccentric roundels 52 on the eccentric roundel mount 50 orderly move in up-and-down reciprocal stroke constantly;

Secondly, meanwhile, five pumping pistons 80 and five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five eccentric roundels 52 to move in up-and-down displacement;

Thirdly, when the eccentric roundel 52 moves in “down stroke” with pumping piston 80 and piston acting zone 74 in “down displacement”, the piston disk 908 of corresponding inlet mount 906 in the piston valvular assembly 900 is pushed into “open” status so that the tap water W can flow into the preliminary-compressing chamber 26 orderly via water inlet orifice 21 in the pump head cover 20 and the group inlet ports 907 of corresponding inlet mount 906 in the piston valvular assembly 90 (as arrowhead indication W shown in FIG. 21);

Fourthly, when the eccentric roundel 52 moves in “up stroke” with pumping piston 80 and piston acting zone 74 in “up displacement”, the piston disk 908 in the piston valvular assembly 90 is pulled into “close” status to compress the tap water W in the preliminary-compressing chamber 26 to increase the water pressure therein up to range of 100 psi-150 psi and become into pressurized water Wp with result that the zone anti-backflow valve 904 in the piston valvular assembly 900 is pushed to “open” status;

Fifthly, when the zone anti-backflow valve 904 in the piston valvular assembly 90 is pushed to “open” status, the pressurized water Wp in the preliminary-compressing chamber 26 is directed into high-compressing chamber 27 via group of outlet ports 905 for the corresponding sector in central outlet mount 902, then expelled out of the water outlet orifice 22 in the pump head cover 20 (as arrowhead indication Wp shown in FIG. 21); and

Finally, with orderly iterative action for each group of outlet ports 95 for five sectors in central outlet mount 902, the pressurized water Wp is constantly discharged out of the conventional five-compressing-chamber diaphragm pump for being further RO-filtered by the RO-cartridge so that the final filtered pressurized water Wp can be used in the commercial reverse osmosis water purification system of large sale, which is popularly installed on the water supplying apparatus in either the settled home, recreational vehicle or mobile home.

The foregoing issues of overall “resonant shakes” and the “water leakage” for the conventional five-compressing-chamber diaphragm pump incurred by the foregoing primary vibrating drawback are also happened in the piston valvular assembly 900. Therefore, how to substantially reduce all the drawbacks associated with the operating vibration for the five-compressing-chamber diaphragm pump becomes an urgent and critical issue indeed.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which has innovative mating means for a pump head body and a diaphragm membrane, where the pump head body includes five operating holes and a basic curved dent circum-disposed around the upper side of each operating hole while the diaphragm membrane includes five equivalent piston acting zones each of which with a acting zone hole, an annular positioning protrusion for each acting zone hole formed, and a basic curved protrusion circum-disposed around each concentric annular positioning protrusion in corresponding position with each mating basic curved dent in the pump head body so that five basic curved protrusions completely insert into corresponding five basic curved dents with a short length of moment arm in generating less torque, which is obtained by length of moment arm multiplying a constant acting force and primarily causes adverse vibration. With less torque, the vibration strength of the five-compressing-chamber diaphragm pump is substantially reduced.

Another object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which has innovative mating means for a pump head body and a diaphragm membrane, where the pump head body has five basic curved dents and the diaphragm membrane has five basic curved protrusions such that five basic curved protrusions completely insert into corresponding five basic curved dents with a short length of moment arm in generating less torque, which is obtained by length of moment arm multiplying a constant acting force and primarily causes adverse vibration. With less torque, the vibration strength of the compressing diaphragm pump is substantially reduced. Having the present invention installed on the housing of the reverse osmosis purification unit on the water supplying apparatus in either the settled home or mobile home pillowed by a conventional cushion base with rubber shock absorber, the harassing noise of the “resonant shakes” incurred in the five-compressing-chamber diaphragm pump can be completely eliminated.

The further object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which includes a cylindrical eccentric roundel disposed in an eccentric roundel mount. The cylindrical eccentric roundel basically comprises an annular positioning dent, a vertical flank and a sloped top ring created from the annular positioning dent to the vertical flank. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred in a conventional tubular eccentric roundel are completely eliminated because the sloped top ring flatly attaches the bottom area of corresponding piston acting zone for a diaphragm membrane. Thus, not only the durability of the diaphragm membrane for sustaining the pumping action of high frequency from the cylindrical eccentric roundels is mainly enhanced. But also the service lifespan of the five-compressing-chamber diaphragm pump is exceedingly prolonged.

The other object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which includes a cylindrical eccentric roundel disposed in an eccentric roundel mount. The cylindrical eccentric roundel basically comprises an annular positioning dent, a vertical flank and a sloped top ring created from the annular positioning dent to the vertical flank. By means of the sloped top ring, all distributed components of the rebounding force for the cylindrical eccentric roundels reacting to the an acting force caused by the pumping action are substantially reduced because the sloped top ring flatly attaches the bottom area of corresponding piston acting zone for a diaphragm membrane.

Thus, some benefits are obtained as below.

1. The durability of the diaphragm membrane for sustaining the pumping action of high frequency from the cylindrical eccentric roundels is mainly enhanced.

2. The power consumption of the five-compressing-chamber diaphragm pump is tremendously diminished due to less current being wasted in the “squeezing phenomena” of high frequency.

3. The working temperature of the five-compressing-chamber diaphragm pump is tremendously subdued due to less power consumption being used.

4. The annoying noise of the bearing incurred by the aged lubricant in the five-compressing-chamber diaphragm pump, which is expeditiously accelerated by the high working temperature, is mostly eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 22 through 31, which are illustrative figures of “five-compressing-chamber diaphragm pump with multiple effects” for the first exemplary embodiment in the present invention.

A basic curved dent 65 is circum-disposed around the upper side of each operating hole 61 in the pump head body 60 (as shown in FIGS. 23 to 25) while a basic curved protrusion 77 is circum-disposed around each concentric annular positioning protrusion 76 (as shown in FIGS. 27 and 28) at the bottom side of the diaphragm membrane 70 in corresponding position with each mating basic curved dent 65 in the pump head body 60 so that each basic curved protrusions 77 at the bottom side of the diaphragm membrane 70 completely inserts into each corresponding basic curved dent 65 at the upper side of the pump head body 60 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 31), as well as a short length of moment arm L2 from the basic curved protrusions 77 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is obtained in the operation of the present invention (as shown in FIG. 31 and enlarged view of association).

Moreover, a cylindrical eccentric roundel 52 in an eccentric roundel mount 50 basically comprises a sloped top ring 58 created from the annular positioning dent 55 to the vertical flank 56 (as shown in FIGS. 29 and 30) to replace the conventional rounded shoulder 57 in each tubular eccentric roundel 52 of the eccentric roundel mount 50 (as shown in FIGS. 3 and 4).

Please refer to FIGS. 32, 33, 15 and 16, which are illustrative figures for the operation of “five-compressing-chamber diaphragm pump with multiple effects” for the first exemplary embodiment in the present invention.

Comparing to the operation of conventional five-compressing-chamber diaphragm pump, a length of moment arm L1 from the outer raised brim 71 to the peripheral of the annular positioning protruding block 76 in the diaphragm membrane 70 is obtained (as shown in FIGS. 15 and 33), a length of moment arm L2 from the basic curved protrusions 77 to the peripheral of the annular positioning protruding block 76 in the diaphragm membrane 70 is obtained in the operation of the present invention (as shown in FIG. 33).

By illustration of foregoing comparative result, it apparently shows that the length of moment arm L2 is shorter than the length of moment arm L1.

While the resultant torque is calculated by same acting force F multiplying the length of moment arm, the resultant torque of the present invention is smaller than that of the conventional five-compressing-chamber diaphragm pump since the length of moment arm L2 is shorter than the length of moment arm L1.

With the smaller resultant torque of the present invention, the vibration strength related is substantially reduced.

Through practical pilot test for the sample of the present invention, the result shows that the vibration strength related is only one tenth (10%) of vibration strength in the conventional five-compressing-chamber diaphragm pump.

If the present invention is installed on the housing C of the reverse osmosis purification unit pillowed by a conventional cushion base 100 with a rubber shock absorber 102 (as shown in FIG. 16), the harassing noise of the “resonant shakes” incurred in the conventional five-compressing-chamber diaphragm pump can be completely eliminated.

Please refer to FIGS. 34 through 36, which are illustrative figures for the operation of the “five-compressing-chamber diaphragm pump with multiple effects” in the first exemplary embodiment of the present invention.

Firstly, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five cylindrical eccentric roundels 52 on the eccentric roundel mount 50 orderly move in up-and-down reciprocal stroke constantly;

Secondly, five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five cylindrical eccentric roundels 52 to move in up-and-down displacement;

Thirdly, when the conventional tubular eccentric roundel or cylindrical eccentric roundel 52 of the present invention moves in “up stroke” with piston acting zone 74 in up displacement, an acting force F will obliquely pull the partial portion between corresponding annular positioning protrusion 76 and outer raised brim 71 of the diaphragm membrane 70;

Please refer to FIGS. 18 and 35. By comparing to the operations between the conventional tubular eccentric roundels 52 and the cylindrical eccentric roundels 52 of the present invention, at least two differences are obtained as below.

In the case of conventional tubular eccentric roundel 52, among all distributed components of the rebounding force Fs, the component force happened at the contacting bottom position P of the diaphragm membrane 70 with the rounded shoulder 57 of the horizontal top face 53 in the tubular eccentric roundel 52 is maximum so that the “squeezing phenomenon” happened here is also maximum (as shown in FIG. 18). With such nonlinear distribution of the “squeezing phenomena”, the obliquely pulling action becomes severe. Whereas, in the case of cylindrical eccentric roundels 52, all distributed components of the rebounding force Fs seem rather linear because the sloped top ring 58 therein flatly attaches the bottom area of the piston acting zone 74 for the diaphragm membrane 70 so that the obliquely pulling action almost eliminated due to no “squeezing phenomenon” (as shown in FIGS. 34 and 35).

Moreover, under the same acting force F, the rebounding force Fs is inversely proportional to the contact area so that all distributed components of the rebounding force Fs for the cylindrical eccentric roundels 52 of the present invention (as shown in FIG. 35) are substantially less than all distributed components of the rebounding force Fs for the conventional tubular eccentric roundel 52 (as shown in FIG. 18).

From above comparison, two advantages are inherited by means of the sloped top ring 58 created from the annular positioning dent 55 to the vertical flank 56 in the eccentric roundel mount 50. First, the susceptible breakage of the diaphragm membrane 70 caused by the “squeezing phenomena” of high frequency, which is incurred by the rounded shoulder 57 of the horizontal top face 53 in the tubular eccentric roundel 52, is completely eliminated (as hypothetically dotted line shown in FIG. 36). Second, the rebounding force Fs of the diaphragm membrane 70 caused by the acting force F, which is incurred by the orderly up-and-down displacement of five piston acting zones 74 in the diaphragm membrane 70 driven by the up-and-down reciprocal stroke of five tubular eccentric roundels or cylindrical eccentric roundels 52, is tremendously reduced.

Therefore, from above inherited advantages, some benefits are obtained as below.

1. The durability of the diaphragm membrane 70 for sustaining the pumping action of high frequency from the cylindrical eccentric roundels 52 is mainly enhanced.

2. The power consumption of the five-compressing-chamber diaphragm pump is tremendously diminished due to less current being wasted in the “squeezing phenomena” of high frequency.

3. The working temperature of the five-compressing-chamber diaphragm pump is tremendously subdued due to less power consumption being used.

4. The annoying noise of the bearing incurred by the aged lubricant in the five-compressing-chamber diaphragm pump, which is expeditiously accelerated by the high working temperature, is mostly eliminated.

Through practical pilot test for the sample of the present invention, the testing results are shown as below.

A. The service lifespan of the diaphragm membrane 70 is exceedingly extended over twice.

B. The diminished electric current is over 1 ampere.

C. The subdued working temperature is over 15 degree of Celsius.

D. The smoothness of the bearing is better improved.

As shown in FIGS. 37 and 38, in the first exemplary embodiment, each basic curved dent 65 of the pump head body 60 can be adapted into a basic curved bore 64.

As shown in FIGS. 39 and 40, in the first exemplary embodiment, each basic curved dent 65 in the pump head body 60 (as shown in FIGS. 23 and 25) and each corresponding basic curved protrusion 77 in the diaphragm membrane 70 (as shown in FIGS. 27 and 28) can be exchanged into a basic curved protrusion 651 in the pump head body 60 (as shown in FIG. 39) and a corresponding basic curved dent 771 in the diaphragm membrane 70 (as shown in FIG. 39) without affecting their mating condition.

Thereby, each basic curved protrusion 651 at the upper side of the pump head body 60 completely inserts into each corresponding basic curved dent 771 at the bottom side of the diaphragm membrane 70 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 40).

Moreover, a short length of moment arm L3 from the basic curved dent 771 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is also obtained in the operation of the present invention (as shown in FIG. 40 and enlarged view of association) so that the newly devised contrivances of pump head body 60 and diaphragm membrane 70 have significant effect in reducing vibration as well.

Please refer to FIGS. 41 through 47, which are illustrative figures of “five-compressing-chamber diaphragm pump with multiple effects” for the second exemplary embodiment in the present invention.

Said five basic curved dent 65 in the pump head body 60 (as shown in FIGS. 23 through 25) can be adapted into a linking five-curved dent 68 to encompass all five operating hole 61 (as shown in FIGS. 41 through 43) while said five corresponding basic curved protrusion 77 in the diaphragm membrane 70 (as shown in FIGS. 27 and 28) can be adapted into a linking five-curved protrusion 79 in corresponding position with the linking five-curved dent 68 in the pump head body 60 to encompass all five annular positioning protrusions 76 (as shown in FIGS. 45 and 46) so that the linking five-curved protrusion 79 at the bottom side of the diaphragm membrane 70 completely insert into the corresponding linking five-curved dent 68 at the upper side of the pump head body 60 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 47), as well as a short length of moment arm L2 from the linking five-curved protrusion 79 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is obtained in the operation of the present invention (as shown in FIG. 47 and enlarged view of association). Thus, the newly devised contrivances of pump head body 60 and diaphragm membrane 70 have significant effect in reducing vibration as well.

As shown in FIGS. 48 and 49, in the second exemplary embodiment, said linking five-curved dent 68 of the pump head body 60 can be adapted into a linking five-curved slit 641.

As shown in FIGS. 50 and 51, in the second exemplary embodiment, the linking five-curved dent 68 in the pump head body 60 (as shown in FIGS. 41 to 43) and the corresponding linking five-curved protrusion 79 in the diaphragm membrane 70 (as shown in FIGS. 45 and 46) can be exchanged into a linking five-curved protrusion 681 in the pump head body 60 (as shown in FIG. 50) and a linking five-curved dent 791 in the diaphragm membrane 70 (as shown in FIG. 50) without affecting their mating condition so that the linking five-curved protrusion 681 at the upper side of the pump head body 60 completely inserts into the linking five-curved dent 791 at the bottom side of the diaphragm membrane 70 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 51), as well as a short length of moment arm L3 from the linking five-curved dent 791 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is also obtained in the operation of the present invention (as shown in FIG. 51 and enlarged view of association). Thus, the newly devised contrivances of pump head body 60 and diaphragm membrane 70 have significant effect in reducing vibration as well.

Please refer to FIGS. 52 through 58, which are illustrative figures of “five-compressing-chamber diaphragm pump with multiple effects” for the third exemplary embodiment in the present invention.

A second outer curved dent 66 is further circum-disposed around each said basic curved dent 65 in the pump head body 60 (as shown in FIGS. 52 through 54) while a second outer curved protrusion 78 is further circum-disposed around each said basic curved protrusion 77 in the diaphragm membrane 70 in corresponding position with each mating second outer curved dent 66 in the pump head body 60 (as shown in FIGS. 56 and 57) so that each pair of basic curved protrusion 77 and second outer curved protrusion 78 at the bottom side of the diaphragm membrane 70 completely insert into each pair of corresponding basic curved dent 65 and second outer curved dent 66 at the upper side of the pump head body 60 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 58 and enlarged view of association), as well as a short length of moment arm L2 from the basic curved protrusion 77 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is obtained in the operation of the present invention (as shown in FIG. 58 and enlarged view of association). Thus, the newly devised contrivances of pump head body 60 and diaphragm membrane 70 not only have significant effect in reducing vibration but also enhance the un-displaceable steadiness in maintenance the length of moment arm L2 for resisting against the acting force F on the eccentric roundel 52.

As shown in FIGS. 59 and 60, in the third exemplary embodiment, each pair of basic curved dent 65 and second outer curved dent 66 of the pump head body 60 can be adapted into a pair of basic curved bore 64 and second outer curved bore 67.

As shown in FIGS. 61 and 62, in the third exemplary embodiment, each pair of basic curved dent 65 and second outer curved dent 66 in the pump head body 60 (as shown in FIGS. 52 to 54) and each corresponding pair of basic curved protrusion 77 and second outer curved protrusion 78 in the diaphragm membrane 70 (as shown in FIGS. 56 and 57) can be exchanged into a pair of basic curved protrusion 651 and second outer curved protrusion 661 in the pump head body 60 (as shown in FIG. 61) and a pair of corresponding basic curved dent 771 and second outer curved dent 781 in the diaphragm membrane 70 (as shown in FIG. 61) without affecting their mating condition so that each pair of basic curved protrusion 651 and second outer curved protrusion 661 at the upper side of the pump head body 60 completely insert into each corresponding pair of basic curved dent 771 and second outer curved dent 781 at the bottom side of the diaphragm membrane 70 upon assembly of the pump head body 60 and the diaphragm membrane 70 (as shown in FIG. 62), as well as a short length of moment arm L3 from the basic curved dent 771 to the peripheral of the annular positioning protrusion 76 in the diaphragm membrane 70 is also obtained in the operation of the present invention (as shown in FIG. 62 and enlarged view of association) Thus, the newly devised contrivances of pump head body 60 and diaphragm membrane 70 not only have significant effect in reducing vibration as well but also enhance the un-displaceable steadiness in maintenance the length of moment arm L2.

Please refer to FIGS. 63 through 69, which are illustrative figures of “five-compressing-chamber diaphragm pump with multiple effects” for the fourth exemplary embodiment in the present invention.

Please refer to FIGS. 119 through 121, which are illustrative figures for the operation in the modified mode of the “five-compressing-chamber diaphragm pump with multiple effects” in a modified mode of for the ninth exemplary embodiment of the present invention.

Firstly, when the motor 10 is powered on, the wobble plate 40 is driven to rotate by the motor output shaft 11 so that five conical frustum eccentric roundel 502 on the eccentric roundel mount 500 orderly move in up-and-down reciprocal stroke constantly;

Secondly, five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five conical frustum eccentric roundel 502 to move in up-and-down displacement;

Thirdly, when the conical frustum eccentric roundel 502 in the present invention moves in “up stroke” with piston acting zone 74 in up displacement, an acting force F will obliquely pull the partial portion between corresponding annular positioning protrusion 76 and outer raised brim 71 of the diaphragm membrane 70; and

Finally, by means of the sloped top ring 508 in the eccentric roundel mount 500, not only the susceptible breakage of the diaphragm membrane 70 caused by the “squeezing phenomena” of high frequency, which is incurred by the rounded shoulder 57 in the conventional tubular eccentric roundel 502 (as hypothetical dotted line shown in FIG. 121), is completely eliminated but also the rebounding force Fs of the diaphragm membrane 70 caused by the acting force F is tremendously reduced. Meanwhile, by means of the inverted conical frustum flank 506, the colliding possibility the conical frustum eccentric roundel 502 with the operating hole 61 in the pump head body 60 is eliminated even the outer diameter of the conical frustum eccentric roundel 502 is enlarged.

Moreover, under the same acting force F, the rebounding force Fs is inversely proportional to the contact area. By means of the enlarged outer diameter of the inverted conical frustum eccentric roundel 502, the contact area of the sloped top ring 508 with the bottom side of the diaphragm membrane 70 is increased (as ring A shown in FIG. 121) so that all distributed components of the rebounding force Fs for the inverted conical frustum eccentric roundels 502 of the present invention are further reduced.

3. The working temperature of the five-compressing-chamber diaphragm pump is tremendously subdued due to less power consumption being used.

4. The annoying noise of the bearing incurred by the aged lubricant in the five-compressing-chamber diaphragm pump, which is expeditiously accelerated by the high working temperature, is mostly eliminated.

5. The service lifespan of the five-compressing-chamber diaphragm pump is further prolonged because all distributed components of the rebounding force Fs for the inverted conical frustum eccentric roundels 502 of the present invention are further reduced.

Please refer to FIGS. 122 through 125, which are illustrative figures of “five-compressing-chamber diaphragm pump with multiple effects” in an adapted mode of for the ninth exemplary embodiment of the present invention.

By means of the enlarged outer diameter of the inverted conical frustum roundel yoke 521, the contact area of the sloped top ring 508 with the bottom side of the diaphragm membrane 70 is increased (as ring A shown in FIG. 129) so that all distributed components of the rebounding force Fs for the inverted conical frustum roundel yoke 521 of the present invention are further reduced.

2. The power consumption of the five-compressing-chamber diaphragm pump is tremendously diminished due to less current being wasted in the “squeezing phenomena” of high frequency.

3. The working temperature of the five-compressing-chamber diaphragm pump is tremendously subdued due to less power consumption being used.

4. The annoying noise of the bearing incurred by the aged lubricant in the five-compressing-chamber diaphragm pump, which is expeditiously accelerated by the high working temperature, is mostly eliminated.

5. The service lifespan of the five-compressing-chamber diaphragm pump is further prolonged because all distributed components of the rebounding force Fs for the inverted conical frustum roundel yoke 521 of the present invention are further reduced.
